The LYNGSØE Class 1 Trousers (ARC-LR4041) are arc rated waterproof trousers for people carrying out outdoor switching, patrol work and other substation tasks in wet weather. Rated Class 1 to IEC 61482-2, they give lower body protection against the thermal hazard of an electric arc while keeping the wearer dry.
LYNGSØE Class 1 Arc Rated Waterproof Trousers
The LYNGSØE Class 1 Trousers (SKU ARC-LR4041) are arc rated waterproof trousers for anyone doing outdoor switching, patrols or maintenance around substations and switchrooms in wet weather. They sit in our arc flash protection range, specifically the waterproof PPE section, so they are built for the days when a standard switching suit would leave you soaked.
Class 1 under IEC 61482-2 is the lower of the two arc protection classes, assessed using the box test method. That is the rating many utilities and contractors in Ireland specify for routine LV and MV outdoor tasks. If you are unsure what the class numbers mean in practice, our page on what arc flash is explains the thermal hazard in plain terms before you pick PPE.

FAQs
What does a Class 1 arc rating mean?
Class 1 is the lower of the two arc protection classes defined by IEC 61482-2, assessed using the box test method. It is widely specified for routine outdoor switching and maintenance on LV and MV systems. Tasks with higher incident energy call for Class 2 garments or arc rated suits matched to your site arc flash study.
Do you supply other LYNGSØE arc rated clothing?
Yes. We supply LYNGSØE across our arc flash range, from waterproof jackets and trousers to other Class 1 and Class 2 garments. If you are matching PPE to an arc flash study, tell our team the incident energy or class you need and we will point you to the appropriate garments.
